A car is traveling at 80 mi/hr. How many hours will it take to cover a distance of 200 miles? Please help and pls add labels please help

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

the closer the planet is to the sun, the larger the gravity

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
